Abstract: A workpiece support that presents a generally planar workpiece contacting surface having high friction, gripping pad(s) that will not mar a workpiece surface, and thus provides a versatile accessory for home hobbyists and artisans alike that protects the supported surface of the workpiece. By providing a non-marring workpiece support, such as that illustrated in FIGS. 1, 8 and 13, to support a workpiece with respect to a work bench surface, the workpiece can be kept from slipping while routing, sanding, carving and the like. It can elevate workpieces for edge work and finishing, or simply suspend and protect projects from marring during drying or between work sessions.

Abstract: A quick connect/disconnect coupling that eliminates the need for tools and the tedious loosening and tightening of hose clamps when detaching and reattaching hoses, such as dust collection system hoses, between machines. The coupling includes a first fitting adapted to be secured to a machine such as a debris generating machine or a dust collector, and a second fitting fixedly secured to a longitudinal end of the associated hose for being partially engaged with and locked to the first fitting. The fittings are preferably translucent or clear so that debris flow can be observed.

Abstract: A clamp pad is provided for being selectively mounted to each jaw of a bar clamp assembly. The clamp pad can be easily mounted to the clamp jaw and radially locked in place with respect to the bar clamp assembly. In an embodiment of the invention, the clamp pad is configured to selectively be fit on either of the clamp jaws of the bar clamp assembly to facilitate assembly. The clamp pad defines a substantially increased clamping area to evenly distribute force and prevent damage to the associated workpiece. The increased dimensions of the clamp pad also stabilizes the bar clamp assembly, which eliminates tipping and thus eliminates the need for associated assemblies such as clamp saddles and the like.

Abstract: A plug cutter is provided that has a main body with a shank extending from one end and plurality of cutting blades extending from the other end. The blades have a plurality of facets defining cutting edges for cutting and shaving stock material to form a plug. The blades define an inner bore having a staged taper and a radial relief portion is provided so that a gap is defined between an outer surface of the plug being formed and the radially relieved portion of the inner surface of the blades. The plug cutter has a built-in depth stop to provide plug height repeatability and quick set up.

Abstract: A plug cutter is described that is rotatable about an axis of rotation. the plug cutter has a main body having a longitudinal axis coinciding with the axis of rotation. The main body defines a bore extending axially therein. A shank extends axially from one end of the main body along the axis of rotation. A plurality of cutting blades extend axially from the opposite end of the main body and each terminate in a distal end. The plurality of blades are adapted to cut a plug from a piece of stock as the plug cutter is rotated about the axis of rotation and advanced axially into the piece of stock. Each of the blades has leading and trailing edges. Each of the blades also has an inner surface and a radially relieved portion facing the bore. The radially relieved portion begins at a relief start position and ends at a relief end position so that, as the plug cutter cuts the plug, a gap is defined between an outer surface of the plug being cut and the radially relieved portion.

Abstract: An attachment that allows a drilling machine, such as a drill press, to simultaneously bore the plurality of holes required for mounting a hardware component to a workpiece. In an exemplary embodiment, the attachment is adapted to simultaneously bore, in a desired disposition, all three holes needed to mount European style hinges in a single stroke. The hinge boring attachment includes a drilling head, which attaches to the chuck of the drilling machine. The drilling head rotatably supports a plurality of boring bit mounting shafts, corresponding to the number of holes to be drilled and interconnected with drive trains for translating the rotation of a center shaft, attached to the chuck of the drilling machine, to all shafts. A stabilizing arm is further preferably provided to clamp the drilling head to the support post of the drill press and roll smoothly along the support post during the drilling operation.

Abstract: A cutter sharpening accessory or cutter holder for use in conjunction with a drill press, radial arm saw or like woodworking apparatus to which a grinding tool, such as a diamond cup wheel, can be secured and rotated at high speed and having a work surface disposed thereunder on which the holder of the invention can be displaced relative to the grinding tool. The cutter sharpening accessory provided in accordance with the invention is adapted to rough and micro adjustment both radially and radial transversely to properly position a cutter to be sharpened relative to the horizontally disposed grinding face of the grinding tool. Continuous adjustment vertically is advantageous provided, furthermore, to ensure that the surface to be ground is properly located vertically relative to the grinding tool.

Abstract: A plug cutter has a main body portion having a longitudinal axis, shank portion extending axially from one end of the main body, and a plurality of blades extending axially from an opposite end of the main body. The blades are formed so that at least a portion of the inner surfaces thereof have a measure of radial relief with respect to the leading edges of the blades. A radial distance from the axis of rotation of the plug cutter to the leading edge of each blade is always less than the radial distance from the axis of rotation to any other portion of the inner surface. Accordingly, when a plug is being cut with the plug cutter, a gap is defined between an outer surface of the plug and the radially relieved portion of the inner surfaces.

Abstract: A depth stop is provided that is selectively attachable to a cutting tool at an operator-selected location. The end of the depth stop that comes into contact with a work piece during operation is covered with a rotating cap. The cap prevents the work piece from being marred because the cap stops rotating when it comes into contact with the work piece while the cutting tool and the rest of the depth stop continue to rotate. The cap is rotatably mounted on the depth stop by a flange that engages a groove formed in the depth stop. An annular ring is provided between the cap and the end of the depth stop body to facilitate the rotatability of the cap with respect to the body.
